<p><P>PROBLEM TO BE SOLVED: To provide a routing control method and a routing controller capable of reducing resource consumption and improving efficiency on the assumption that the inter-node connectability of a low-order network is ensured at executing routing for a virtual network without any hierarchical structure. <P>SOLUTION: A service address and a session are managed, and the location of each application and the location of each proxy are managed as a resource table, and the corresponding relation of the destination application and the other proxy in the next hop is managed as a proxy routing table, and the network address of the communication device of each node is managed as a location table. When information is updated, or information retrieval is necessary, a message is transmitted to the other nodes managed by each table, and when any retrieval message information is not present, or an updated message is received, the message is transmitted to the other nodes unless the number of hops exceeds a limit value. <P>COPYRIGHT: (C)2003,JPO</p> |
